My swirl finders have all died
Do any of you use this machine to find defects? Any other suggestions?

You can always make your own "Sun Gun"...at a much lower price-point!!Any other suggestions?
Yet more evidence that, to make your own Sun Gun:3M gun is made for paint matching, not really aimed for swirl finding. Meaning that a brinkman performs 95% as good as this to see swirls. Also the battery life in these suck. Maybe 10-15 minutes until you need to charge again. And the bulb is expensive and has a short life.
^^^Yes indeedy^^^...There's a diy for sun guns. I'm actually about to try it myself since my brinkmann no longer works.

Yet more evidence that, to make your own Sun Gun:
Is the way to go...Especially if it's both AC and DC operated!!
And even though it's designed for color-matching...
I beg to differ on the Sun Gun's ability in finding swirls.

I even made one. And in my waning-years in Life, no less!!

-I never said that a Sun Gun was 10X better than a Brinkman for swirl finding.I know what you are saying Bob.
I just find for swirl finding it isn't 10x better than a brinkman.
Make your own!
I have found the link for the diy,, pm me. I just sent info to Tundra
